Torulaspora delbrueckii: aplicaciones tecnológicas y aislamiento de genes de respuesta a estrés.
2005
Durante los últimos años la producción de masas congeladas para bollería ha experimentado un notable incremento. La calidad de estos productos está lejos de la que se obtiene a partir de masas frescas Esto es debido a la sensibilidad al proceso de congelación y descongelación de S. cerevisiae y a la reducción de su capacidad fermentativa durante el almacenamiento. Si las masas congeladas son azucaradas el problema es todavía mayor. En la elaboración de masas dulces se utiliza hasta un 30% de azúcar provoca una fuerte reducción de la actividad de agua generando ambientes de alta presiones osmóticas. Como consecuencia de todo esto el tiempo de fermentación de estas masas se prolonga y el volu…
Physicochemical and technological properties of beef burger as influenced by the addition of pea fibre
2019
This study aimed to evaluate the physicochemical characteristics and sensory attributes of beef burgers with the addition of pea fibre as a partial substitute of meat or fat. Three formulations were prepared: control (CON) – similar to the commercial formulation; fibre/less meat (FLM)—5% meat reduction and addition of 1% pea fibre; fibre/less fat (FLF)—7% fat reduction and addition of 1% pea fibre. Non‐significant differences were obtained for pH, colour parameters (L* and b*), texture profile, cooking loss and size reduction among formulations. Moreover, sensory analysis with consumers of beef burgers did not indicate differences among the formulations for all the analysed attributes. Ther…
Stabilization process in Saccharomyces intra- and interspecific hybrids in fermentative conditions
2015
© 2015 Sociedad Española de Microbiologia. All rights reserved. We evaluated the genetic stabilization of artificial intra- (Saccharomyces cerevisiae) and interspecific (S. cerevisiae × S. kudriavzevii) hybrids under wine fermentative conditions. Large-scale transitions in genome size and genome reorganizations were observed during this process. Interspecific hybrids seem to need fewer generations to reach genetic stability than intraspecific hybrids. The largest number of molecular patterns recovered among the derived clones was observed for intraspecific hybrids, particularly for those obtained by rare-mating. Molecular marker analyses revealed that unstable clones could change during the…
Development of new non-dairy beverages from Mediterranean fruit juices fermented with water kefir microorganisms
2016
The aim of this work was to explore the use of several Mediterranean fruit juices as fermentable substrates to develop new non-dairy fermented beverages. Microbiological, chemical and sensory features of kefir-like beverages obtained after the fermentation of juices extracted from fruits cultivated in Sicily (southern Italy) with water kefir microorganisms were investigated. Results indicated that both lactic acid bacteria and yeasts were able to develop in the fruit juices tested, but the highest levels were registered with prickly pear fruit juice. All fruit juices underwent a lactic fermentation, since a lactic acid content was detected in the resulting kefir-like beverages. Except kiwif…

AnMBR, reclaimed water and fertigation: Two case studies in Italy and Spain to assess economic and technological feasibility and CO2 emissions within…
2020
[EN] The use of anaerobic membrane bioreactor (AnMBR) technology on urban wastewater can help to alleviate droughts, by reusing the water and nutrients embedded in the effluent in agriculture (fertigation) in line with Circular Economy principles. The combination of AnMBR and fertigation reduces CO2 emissions due to the organic matter valorization and the partial avoidance of mineral fertilizer requirements. However, both AnMBR and fertigation still face technological and regulatory barriers that need to be overcome. These bottlenecks were tackled within the first Innovation Deal approved by the European Commission in 2016, and gave rise to several case studies on water reuse systems. The r…
La soluzione italiana alla crisi delle filiere agroalimentari: il decreto legge 19 marzo 2019, n. 27
2019
L’Autore affronta il tema della regolazione della filiera agroalimentare e dei tentativi di porre rimedio ai fallimenti del mercato . Analizzando i recenti interventi normativi in risposta alle gravi crisi del comparto lattiero-caseario, emergono difficoltà e incertezze del legislatore e del governo italiano nell’affrontare queste criticità, che sono legate all’assenza di un’adeguata regolazione di tipo contrattuale . Inadeguatezza che può essere affrontata e risolta puntando su di un mutamento di approccio e considerando che le relazioni contrattuali di filiera necessitano di interventi proporzionati, più efficaci ed efficienti, in grado di esaltare i momenti di autonomia contrattuale disc…
